#include <winsvc.h>
void CStartServiceDlg::OnBnClickedButton1()

    {
        TRACE( "open SCManager error");
        return;
    }
    // 打开www服务。
    SC_HANDLE hSvc = ::OpenService( hSC, "W3SVC",
        SERVICE_START | SERVICE_QUERY_STATUS | SERVICE_STOP);
    if( hSvc == NULL)
    {
        TRACE( "Open www erron。");
        ::CloseServiceHandle( hSC);
        return;
    }
    // 获得服务的状态
    SERVICE_STATUS status;
    if( ::QueryServiceStatus( hSvc, &status) == FALSE)
    {
        TRACE( "Get Service state error。");
        ::CloseServiceHandle( hSvc);
        ::CloseServiceHandle( hSC);
        return;
    }
    //如果处于停止状态则启动服务，否则停止服务。
    if( status.dwCurrentState == SERVICE_RUNNING)
    {
        // 停止服务
        if( ::ControlService( hSvc, 
          SERVICE_CONTROL_STOP, &status) == FALSE)
        {
            TRACE( "stop service error。");
            ::CloseServiceHandle( hSvc);
            ::CloseServiceHandle( hSC);
            return;
        }
        // 等待服务停止
        while( ::QueryServiceStatus( hSvc, &status) == TRUE)
        {
            ::Sleep( status.dwWaitHint);
            if( status.dwCurrentState == SERVICE_STOPPED)
            {
                AfxMessageBox( "stop success。");
                ::CloseServiceHandle( hSvc);
                ::CloseServiceHandle( hSC);
                return;
            }
        }
    }
    else if( status.dwCurrentState == SERVICE_STOPPED)
